(Summary description)Introduction of oil casing. Steel grade of oil casing: H40, J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. Processing form of casing end: short round thread, long round thread, partial trapezoid thread, special buckle, etc. It is mainly used for oil well drilling to support the well wall during the drilling process and after completion to ensure the progress of the drilling process and the normal operation of the entire oil well after completion.

Introduction of oil casing. Steel grade of oil casing: H40, J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. Processing form of casing end: short round thread, long round thread, partial trapezoid thread, special buckle, etc. It is mainly used for oil well drilling to support the well wall during the drilling process and after completion to ensure the progress of the drilling process and the normal operation of the entire oil well after completion.

Different types of casing used in the process of oil extraction: surface oil casing protects the drilling to avoid contamination by shallow water and gas layers, supports wellhead equipment and maintains the weight of other layers of the casing. Technical oil casing separates the pressure at different levels so that the drilling fluid can circulate normally and protect the production casing. In order to install anti-burst devices, leak-proof devices and tail pipes in the well. Reservoir oil casing leads oil and natural gas from the reservoir below the surface. It is used to protect wells and layer drilling mud. When the oil casing is produced, the outer diameter is usually 114.3 mm to 508 mm.
